GRAVlTY PIN-LlFTER FOR CAR-COUPLINGS.

QEEGIFEOA'EION formingpart of Letters Patent No. 719,096, dated January27, 1903. hpplication filed November 18,1902. Serial No. 131,886. (Nomodel.)

a, whom it may concern:

Be it known that 1, WILLIAM DIEVEN- DORF, a citizen of theUnited States,residing at Sprakers, in the county of Montgomery and State of NewYork,have invented certain new and useful Improvements in Gravity Pin-Lifters for Car-Couplers; and I do declare the following to be a full,clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference beinghad to the accompanying drawing, and to the let'-ters of reference marked thereon, which forms a part of thisspecification.

This invention .relates to new and useful improvements in means foruncoupling cars, and especially in the provision of a gravity pinapparatus whereby the pin held in the couplers may be raised or loweredwithout the necessity of the operator going between the cars.

More specifically, theinvention consists in the provision of means forraising the pin from the car-coupler by means of alongitudinally-movable rod mounted on the end of the car and having aneye formed in one end, through which a bar has slight movement, wherebythe pin may be lifted from the lower portion of the car independently ofthe longitudinal rod.

My invention consists, further, in various details of construction andcombination of parts, which will hereinafter be more fully described andthen specifically set forth in the appended claims.

My invention is illustrated in the accompanying drawing, in which I haveshown a perspective view of the device attached to the end of a car,said view showing on dotted lines the operative parts raised to theirhighest limit. a

Reference now being had to the details of the drawing by letter, Adesignates the end of the car, and B a bail-shaped member which isjournaled in suitable bearings C on the end of the car. The inner end ofsaid bail-shaped member has pivotal connection with the pin D, adaptedto fit through the coupler, while the other end of said bail-shapedmember forms a handle, whereby the pin maybe drawn out of the couplerfrom the lower portion of the car. Said member B is bent to form a crankE, to which crank portion a bar F is pivotally connected, the upper endof said bar being provided with a head F and is guided by means of aneye K, attached to the end of the car.

A rod N is held to the end of the car by means of eyes N and has alongitudinal movement, the upper end being positioned adjacent to theroof of the car and provided with a suitable loop or handle, while itslower end is bent at right angles into an eye M, through which said baris passed. When the rod N is at its lowest limit, the eye M is adaptedto rest against an eye K, carried by the end of the car, in whichposition it will be observed that the bail-shaped member may be raisedand lowered, and also the bar F, independently of the rod N, thusenabling an operator to raise a pin out of the coupling without going tothe top of the car to operate the rod N. When the operator desires fromthe roof of the car to raise the pin, the same may be done by pulling upon the rod N, which will cause the eye at the lower end thereof tocontact with the end of the bar F and raise the latter, which will causethe bail-shaped memher to rock and the pin to be raised out of thecoupling. By releasing the rod the pin will drop to its lowest positionby gravity.

From the foregoing it will be observed that by the provision of anapparatus as shown and described an efficient means is had of raisingand lowering the pin and couplers without the necessity of an operatorgoing between the cars and also by means whereby the pin may be raised,if desired, without operating the same from the roof of the car.

While I have shown the particular details of construction of theapparatus illustrating my invention, it may be observed that I may makeslight alterations in the construction of the same without departingfrom the spirit of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A pin-liftingapparatus for car-couplers, comprising in combinationwith a bail-shaped member pivoted on the car, a pin pivotally connectedto one end of said member, a bar having pivotal connection with thecrank portion of said member, an eye, fastened to one end of the carthrough which said bar is guided, a longitudinally-movable rod held tothe end of the car, the lower end of said rod turned into an eye atright angles to the length of the rod and through which said bar passes,a head on the upper end of said bar against which the lower end of therod contacts to raise the bar and rock the bail-shaped member, wherebythe pin may be raised out of the coupler, as set forth.

2. A pin-lifting apparatus for car-couplers, comprising in combinationwith the car a bailshaped member mounted to rock in suitable bearings onthe end of the car, a pin pivoted to one end of said member, a barpivotally connected to the crank portion of said bail member, aguide-staple carried by the car and through which said bar passes, alongitudinally-movable rod, eyes carried by the car and through whichsaid rod passes, the lower end of said rod being bent at an angle, andinto an eye through which said bar passes, said lower end of the rodadapted to contact with said staple to limit its downward throw and tocontact with the head of the bar to raise the latter and cause the bailto rock and to lift the pin from the coupler, as set forth. In testimonywhereof I hereunto afiix my signature in presence of two witnesses.

WILLIAM B. DIEVENDORF.
